Kendo UI Upload Async Error

[Stephen]

I'm testing my new Kendo Upload tool in an MVC site. I've found in our XP QA machine, using any version of IE, I'm not able to upload any images (I've set to only allow .jpg). I get a permission denied error in my XMLHttpRequest response.

I believe this is because we're showing the MVC site inside of an iframe of another site, and we're getting some kind of cross-domain issue. However if this were the case, would it only be happening in an XP environment, or all of them? Does anyone know enough about Kendo to point me in the right direction?

    @(Html.Kendo().Upload()
        .Name("images")
        .Async(async => async
            .Save("Save", "Upload")
            .Remove("Remove", "Upload")
            .AutoUpload(true)
        )
        .Events(events => events
            .Select("onSelect")
            .Remove("onRemove")
            .Error("onError")
            .Upload("onUpload")
            .Success("onSuccess")
        )
    )

Hi,

I tried reproducing the issue by hosting the Upload demos in an IFRAME as shown here. This worked fine in IE8 on XP.

That said, we have received similar reports before, but we're unable to pinpoint the exact scenario that triggers the problem.

All the best,
